1966 kawasaki F1

[mufins13]

i picked this bike up when i was like 8 and it has sat in my shed ever since. so the other week i rolled it out, put a newer tank on it with no rust. washed her off and fired her right up! rode around the yard checking brakes and lights and such, shes only got 4,ooo miles on her. ok long story short the clutch cable broke into about ten pieces.  can some one tell me how long it should be from end to end?
